Our sun may have a stealth companion that disturbs comets from the edge of the solar system — a giant planet with up to four times the mass of Jupiter, researchers suggest. A NASA space telescope launched last year may soon detect such a stealth , if it actually exists, in the distant icy realm of the comet-birthing Oort cloud, which surrounds our solar system with billions of icy objects. The potential giant Jupiter would likely be a world so frigid it is difficult to spot, researchers said. It could be found up to 30,000 astronomical units from the sun. One AU is the distance between the Earth and the sun, about 93 million miles.

The giant planet is hidden in our Solar System according to scientists John Matese and Daniel Whitmire, from the University of Louisiana at Lafayette. According to the team, a colossus called Tyche is hidden in the Oort Cloud—the asteroid beehive that forms the outer shell of our home system, one light-year in radius. They claim that data already captured by NASA's Wide-field Infrared Survey Explorer proves its existence.

Matese and Whitmire are convinced that Tyche composed mostly of hydrogen and helium is very real orbiting 15,000 times farther from the Sun than Earth, orbiting the Sun with moons and rings and an athmosphere with clouds and storm systems similar to Jupiter with a mild temperature (-73ºC/-99.4ºF).

If Tyche's existence is confirmed, its Solar System planet status may not be debated that Tyche could be a planet born in another star system and captured by ours.
